China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Compared with the long-term use of magnetic ballasts, electronic ballasts saving effect significant saving principle embodied in the following four aspects
1.1 increase in light output. Improve the efficiency of lighting.
1.2 low power consumption. The various gas discharge lamp magnetic ballasts power consumption is typically about 20% of the lamp power. Ceramic metal halide electronic ballast power consumption can be as low as 7%. Electronic ballasts, energy-saving effect is obvious. In the case of the same electronic ballast own loss, the larger the lamp power, the energy saving effect is more remarkable.
1.3 has a high power factor. Using magnetic ballasts, power factor is typically only 0.5 to 0.6. Electronic ballasts, power factor correction measures taken by the system power factor can easily reach more than 0.95, even reach a level very close to 1, which is difficult to achieve using magnetic ballasts. Improve power factor of the line, under the conditions of the same generation and substation equipment, validated the ability to improve power supply and power utilization, improve the quality of power supply, and save a lot of energy. Shown below, in full-wave rectifier with large-capacity electrolytic capacitors asked to set up a power factor correction (PFC) boost conversion circuit, its role is to get the low current harmonic distortion, high power factor.
1.4 having a constant power output characteristics, when the input voltage rises, the input power of the magnetic ballast is significantly improved, and the life of the discharge lamp to have an impact, and the electronic ballast when the input is between 160V ~ 270V, the output power remain unchanged. Shown below, the control circuit for a gas discharge lamp in the power detection and feedback to maintain the output power constant.
